Dogs are native to that Americas. Cats are an invasive species that were
brought by Europeans. Cats kill BILLIONS of song birds each year and spread
a dangerous parasite, toxoplasmosis, with is linked to mental illness.
Previously it was thought that only infants were susceptible but recent
studies have shown that forty percent of humans have caught the parasite
from cats and one percent of those have to do parasite related mental
illness. This cat parasite lays larva in the brain. So if you insist on
having one of these beasts then surely have it neutered and in a generation
the problem will be solved

I agree with Aaron that it is totally unfair for the dog to be denied
equality with the cat but far more important are the health risks posed by
cats.

Furthermore the myth that cats are clean is broken once you smell cat urine
or cat shit., far fouler than anything from a dog and a vector for
dangerous disease.﻿
